The bar or work piece is thenadvanced again and the preliminary forging is made into a final forgingby cooperating dies of the desired formation, while the roller and thepreliminary dies are effective on the succeeding portions of thev baradvanced to their respective positions. Thus the bar emerges at the rearof the machine completely forged into attached hinges with acomparatively small Hash or trimmed scrap loss.

The movable dies, which are the upper` dies in the form of the inventionherein set forth, are operated from a plunger which is connected to anupper crank shaft. This crank shaft also operates the roller through asuitable cam connection which provides the required dwell, and throughan eccentric connection which produces the longitudinal movement of theroller.

The crank shaft is also connected to a feeding frame provided withgrippers which' are automatically engageable with and disengageable fromthe metal bar at the proper time in the sequence of operation.v At thefront of the press and engageable with the unformed bar is one set ofgripping devices, and at the rear of the press are additional grippingdevices arranged for engagement with either the upper and lower sides ofthe formed hinges or else for engagement with' the sides of the hinges,for holding the series of hinges against longitudinal movement duringthe forming operations, but causing the advance of the series of hingesat the proper time after the forming dieshave been separated'.

The bar feeding mechanism operates 'step by step during the entire pressoperation, and in order to permit a heated bar to be inserted into thefront feeding grippers and in proper relation with the forging dieswithout stopping the machine a lockout is provided adapted for operationat a predetermined time in the sequence of press operations but underthe manual control of the operator, whereby the front grippers can beheld apart to provide for the insertion of the heated bar, theconstruction also being such that a locating screw is raised into theproper position for locating the end of the work bar so that it willhave the proper relation to the roller and forging dies at the time itis engaged by the grippers.

Referring now more particularly to the drawings by reference numerals,10 represents the frame, ll-the stationary bed, and 12 the main crankshaft'of a press. Power is supplied to 'the crank shaft 12 throughsuitable gearing 13 from an electric motor 14, the crank shaft beingconnected through the connecting rod 15 to cause vertical reciprocatorymovements of the upper die supporting member 16 which is suitably guidedin the press frame.

The crank shaft 12 is connected by gears 18 to a horizontal shaft 19' onwhich are cams 20\and 21, see Figs. 2 and 3. The cam 20 is engaged by aroller 20 while roller 21' engages cam 21. The rollers 20 and 21 arerotatably carried on a frame 22 which is oscillatably or pivotallymounted on an axis 22. The frame 22 is also pivotally connected at 23 toa link 24. The construction 4just described is such that as the cams 29and 2i are rotated counter-clockwise as shown in Fig. 3, at the samespeed as the crank shaft, the frame 22 is rotatably oscillated under thepositivecontrol of the two cams and the two rollers, producing apositive vertical reciprocatory movement of the link 24.

The lower end of the link 24 is pivotally connected as by a ball andsocket joint 26 to the roller carrier 27 which is slidably guided forvertical movement on the front side of the press fratrie.. As shown inFigs. 3 and 4, the roller carrier 27 movably supports the slide 28 forhorizontal motion therein, the slide and the roller car- Arier havingcooperating guide or slide surfaces 30.

The slide 28 is symmetrical in form, as shown in t Fig. 4. In it isrotatably mounted the shaft 31 of the roller segment 32. Keyed to theshaft 31 is a rack segment 33 engageable with rack teeth 34 on theroller carrier. A slot 35 is preferably provided in the side of theroller carrier to nfacilitate lubrication of the parts. It will beunderstood that a segment gear and rack are provided at 'each side ofthe roller, causing vthe roller to move the shaft 19. The relationshipof the parts shown in Fig. 3 is such that with the plunger down andready to ascend, the roller is at the left-hand end of its stroke and ina depressed or dwelling position but ready to start moving upwardly.

By means of the roller operating mechanism as just described `it will beapparent that the roller may be forced down into the heated bar of metalwhich rests on the fixed base 40 ahead of the die position, dwelling inits down position for about 180 movement of the crank shaft during whichmovement the arm 38 is operated through its eccentric driving connectionwith the cam shaft to force the roller to the left as viewed in Fig. 3.The roller segment 32 is so timed, and its stroke is such, that the barwill be very materially reduced in thickness throughout a substantialporgagement between the preliminary forming dies and 46 which partiallyform the length of bar including theunrolled portion 42 into a shapeap.-A proxirnatingr the desired final shape. During the time thepreliminary dies 45 and 46 are effective on the work, the roller 32 iscompleting the rolling of another flattened portion on the succeedinglength of work. The bar is then fed forwardly again between thefinishing dies 47 and 48 which produce the nal shape desired. The dies45 and 47 are movable together and are both attached to the lower sideof the press plunger. The lower dies 46 and 48 are held on the pressbed. A knockout bar 50 is preferably provided in the upper die andarranged to be forced downwardly for ejecting the formed article fromthe upper die by means of a pin 51 provided in the per end of pin 56which is reciprocated by anv arm 57 connected to link 58 'adapted tobe'reciprocated at the proper time in the sequence of operations byroller and cam means designated generally 59, see Figs. 1 and2. 'Iheupper end of the pin 56 is normally flush with the bottom .of the lowerdie 48.

As herein shown, the lower dies 46 and 48 are Y provided on a slideblock 60, see Fig. 1, so that 48 are of identical ,form and constructionbut are cool.

adapted for successive cooperation with the upper dies in vorder thatthe lower dies may be kept The means for reciprocating the-die carryingblock comprises a link 6l, bell-crank 62, slide 63, link 64, arm 65,-androllers 66, 67 engageable respectively with cams 66' and 67' on a shaft68, which is connected by gearing 69 to the cam shaft 19, theconstruction being such that for each revolution of the crank shaft oneset of roller dies will remain xed in position and the dies will then beshifted to bring the other pair of lower dies into proper alignment withthe upper dies while the plunger is in an upper position.

Referring now more particularly to Figs. 1 and 5, the feeding means bywhich the bar is advanced in a step by step manner comprises a feedingframe 70 embodying laterally spaced bars 71 and 71 guided forlongitudinal movements in bearing brackets 72 on the press frame. At thefront end of the bars 71, 71 are the front grippers 73, '74 which arearranged for engagement with the sides of the heated bar. The grippingdevice 73 is detachably set in a. desired position by means of theadjusting screw 75. The opposite gripping device 74 is adjustablysecured on a plunger 76 which is guided in the carrier 77'for horizontalsliding movement. The outwardly extending end of the plunger 76 isprovided with projections 78 between which is arranged an arm 79 nxed toan oppositely projecting arm 80 and pivotally supported on the axis 8l.The arm 80 is adapted to be operated by projections 82 on a springpressed bar 83. The operating spring 84, for the bar 83 yieldingly urgesthe bar 83 toward the right as viewed in Fig. 6 thus tending toyieldingly hold the gripping device l'74 against the work. The bar 83 isrigid with a roller carrier 86 on which a roller 87 is rotatablymounted. This roller 87 opcrates on a flat plate 88 which is shown inits retracted position in Fig. 5, but which is adapted to be moved tothe left at the proper time in each cycle of operations of the press inorder-to release the gripping device 74 from the work. When the plate 88is moved to the left the roller 87 and the bar 83 are forced to the leftagainst the action of the spring 84, thus positively pulling thegripping'device 74 toward the right and releasing the work. Y It will beunderstood that the entire feeding ,frame and gripping device are movedconstantly back and forth during pressk operations,-

the roller 87 operating on the plate 88 which is arranged parallel tothe path of movement o f the feeding device so that feeding movements ofthe frame are without eilect on the grippers.

The plate 88 is slidably guided 0nthe press frame for horizontalreciprocatory movements. A link 90 is pivotally connected to the plate88 and to a double armed lever 91 which is pivotally connected to areciprocatory bar` 92. When this bar 92 moves horizontally in onedirection (upwardly as viewed in Fig. 5) the plate 88 is moved to theAleft. The bar 92 is moved in the direction of its length by means ofcams 93 and 94 on the cam shaft 19 engaged by cam rollers 93 and 9'4carried by arms both of which are fixedl to the rock arm 95 which ispivotallyconnected to a link 96 as shown in Figs. Iv and 2. The lowerend of the link 96 pivotally connects toaI bell-crank lever 97, thelower end of which is provided with a bifurcated slide guide embracingthe block 98 which is suitably held on the bar or rod 92. The cams 93and 94 are so formed as to provide 'a positive movement of the bar 92 inboth directions and at the proper time in the sequence of pressoperations so that the gripping device 74 is released from the work whenthe feeding frame moves forwardly but is engaged with the work duringthe rearward or feeding movement of the feeding frame in order to causethe work to move with the feeding frame 'throughout a complete feedingstroke. as shown in Fig. 11, is at a time when the roller 32 and theupper dies 45 and 47 are raised. It will be seen from the figure men--tioned that the point in the cycle of press operations at which thefeeding movement takes place is just before the plunger descends, thegrippers being open during the time the roller is flattening out thework piece.

The advancing end of the formed work is also adapted to be held duringfeeding movements by suitable gripping devices so that the bar is pulled.100

as well as being pushed in a step by step manner. 'I'he rear grippingdevices which are adapted for engagement with the formed hinges areshown in Fig. 7 and at the upper portion of Fig. 5. The

rear gripping devices are so arranged that the work may be held eitherat the sides or at the top and bottom as desired, as it will be readilyunderstood that with an article such as a hinge having substantially`constant width and having a thickness whichvaries at different portionsof the hinge it will be advantageous to grip the formed articles on thesides although other articles of a different form might better begrippedV at the top andbottom. The' two grippers 100 and 101 aretherefore provided at the rear of the feeding frame, gripping device 100being adjust'- ably secured in support while gripping device 101 isadjustably held in a reciprocating plunger 102, reciprocally mounted insupport 111, in substantially the same manner as has previously beendescribed with reference to the forward gripping devices. The plunger102 is operated by a double armed lever 103, which is controlled by thebar l 104 influenced by a spring 105 which normally tends to urge thegripping device 101 away from the work in the same manner as haspreviously been described with reference to the forward grippers. Thebar 104 is controlled by a roller 106 operating on a flat plate 107which is controlled by the rod 92 so as to move simultaneously with andin the same direction as the plate 88 so that the rear grippers will beengaged with the work or disengaged from the work at the same time thefront grippers are correspondingly moved; In the solid line positionshown in Fig. 7, the grippers'100 and 101 are engageable with the sidesof the work. However these grippers are vreadily removable from the'supporting parts 110 either' a vertical or horizontal direction depend-150 ent on its position in either the support 110 or support 110a. Bothgrippers 100 and 101 may be so adjusted with respect to its holding oroperating means that it advances yfar enough toward the work foreiective gripping action.

The feeding frame including the side bars 71, 71' 4and the end framemembers at the front and rear of the press which support the grippers isbodily movable in a reciprocatory manner, being pivotally connected to alink member 119, see Figs. 5 and 8, the rear portion of the link member119 being pivoted to an arm 116 which is secured on the oscillatoryshaft 117. An operating element 118 is fixed to the shaft 117 and to thearm 116 and is pivotally connected to the feed operating link 120 whichextends upwardly to link 121, operated by cams 122 and 123 engaged byrollers 122' and 123 on arms rigid with n the link 121. The cams 122andl 123 are provided `forward grippers may be locked out so that theycannot engage the work, in order that a new bar can be inserted betweenthe front grippers without stopping the press. This lockout is under themanual control of the operator, the construc- 1 tion being shown moreclearly in Figs. 2, 6, 8

and 9. At the proper time in the sequence of Voperations a pin 125 maybe raised vertically upwardly so as to come into the path of movement ofa lug 126 provided on the bar 83 of the gripper operating mechanism, ata time when the gripper '74 is released from the work. Then after theplates 88 and 107 are moved to retracted positions the bar 63 will beprevented from returning and the grippers will be held open. This pin125 is provided on an arm 127 secured to the 'upper end of a bar 128.The lower end of the bar 128 is controlled by an arm 129 to which issecured a gear segment 130 and to which is also secured a lever pivotedto the upper end of a release link 131. The gear segment 130 is inengagement with a gear segment 132 xed with relation to arm 133, arm 133engaging the lower end of a bar 134 which is fixed to a threaded rod 135normally urged upwardly under the control of the spring 136. The springtension may be adjusted by means of the nuts 137 on rod 135. This springtends to move the plunger 134 upwardly and to move the control link 131upwardly although normally the control link 131 is held in a loweredposition by the foot bar 139 having a gravity actuating lock 140 whichnormally holds the foot bar 139 in'a depressed position as shown in Fig.6. However, when the step 141 of the gravity lock is depressed, thedepending arm 142 is movedaway from over the foot bar 139 permitting the'latter to be moved up under the action of the spring 136. When the bar139 is moved up under the action of the spring the pin 125 is projectedso as to hold the front grippers open ready for the insertion of a bar.Such raising action of thebar 139,' however, can only take place afterthe lug 126 is moved out of the path of the pin 125, the foot bar 139being held down until the lug 126 moves clear of the pin and opens thefront grippers.

At the same time the pin 125 is raised to lock out the front grippers, alocating screw 146 (Fig. 8) is elevated. The head of the screwiforms seeFig. 8.

an abutment for the advancing end of the work thus locating the work inthe properposition with respect to the feeding and gripping mechanism atthe time the closing of the front grippers takes place. The locatingscrew 146 is adjustably threaded in a frame 147 carried for verticalsliding movement in a bracket 148 on the press frame. The frame 147 issecured to the upper end of plunger 134 so that as the plunger 134 movesup the locating screw will be moved up from a normally retractedposition below the path of -the bar, see Fig. 8, into the path ofmovement of the front end of the work bar.

The locating screw 146 is moved toa retracted i position at the sametime the lockout pin 125 is retracted, since these two devices areinterconnected by the mechanism previously described including the racksegments 130 and 132. After a new bar is inserted between the frontgrippers with its advancing end against the locating screw, and theoperator desires to have the front grippers close and the locating screwmove down, he presses on the foot bar 139, thus moving the lockout pin125 down so that the front grippers can be closed and also pulling downor retract ing the locating screw. Such movements, however, of the pin125 and locating screw can only take place at the proper time inthesequence of operations, because the oar '139 is held in its upperposition after having moved to that position, by means of a holdinglever 150 xed with respect to the arm 129 and gear segment 13'0, Thislever 150 is provided with a curved seat 151 which is adapted to beengaged by the side of a plunger 152 after the lever 150 has been swungto the right from its normal position due to the upward movement of thefoot bar 13'9. The pin 152, shown in Figs. 5 and 9,

is slidably guided so as to be projectedinto the return path of movementof lever 150, being operated by link connections 155, 156 and 157 to anarm 158 provided on a shaft 159 which is controlled by the 'bar 92, itbeing remembered that the bar 92 is moved endwise by cams operated fromthe crank shaft to cause the engagement and disengagement of thegrippers. When the arm 158 is moved over to the right from the positionshown in Fig. 9, the pin or plunger 152 tends to be projectedinto'the'path of movement of the lever 150, but if the lever 150 is infront of the plunger, a spring 160 provided on the link 157 iscompressed so that the plunger l152 can be projected subsequent to theraising of the foot bar 139. When the foot bar-139 is in its depressedposition and the gripping as well as the feeding devices are operativelyassociated with the press mechanismthe compression spring 160y isoperated without causing the projection of the holding plunger 152'.

It will, therefore, be apparent that without stopping the operation ofthe plunger and with out stopping the reciprocatory feeding operationsof the feeding frame, the -front grippers may be held open and thelocating screw may be raised so that the bar can be inserted between themoving grippers, 'and at the proper time in the sequence of operationsthe operator is enabled topress the foot bar 139 down against the actionof the spring 136 and move the lockout pin 125 so as to permit thenormal functioning of the front grippers, thisaction also retracting thelocating screw out of the advancing path of movement of the bar of work.Then when the grippers move the work forwardly the end of the work piecewill be in a proper position with :,ovaaso respect tothe roller so thatthere will be no waste or scrap loss ofthe first article formed.

While the method herein described, and the form of apparatus forcarrying this method into effect, constitute preferred embodiments ofthe invention, itis to'be understood that the invention is not limitedto this precise method andv form of apparatus, and -that changes may bemade in either without departing from the scope of the invention whichis defined the appended claims.
